state effect of 1) surface area 2) nature of the liquid on rate of evaporation
is it possible to liquify atmospheric gases ? if yes suggest a method
these question teacher has given for exam coming bt i dont know the answer because it is a difficult question pls expert help me otherwise my teacher will scold me and i will commit suicide pls answer pls
Surface area- Rate of evaporation increases with the increase in surface area of the liquid since evaporation is a surface phenomenon.
Nature of liquid-More volatile liquid evaporates faster than the less volatile liquid.
Yes, atmospheric gases can be liquefied by applying pressure and reducing temperature.
SURFACE AREA AFFECTS THE RATE OF EVAPORATION BECAUSE THE LARGER THE AREA THE HIGHER THE RATE OF EVAPORATION AND LESSER THE AREA THE LESS THE RATE OF EVAPORATION.FOR EXAMPLE IN SEA EVAPORATION RATE IS HIGHER THAN WATER IN A SMALL CUP.THIS IS BECAUS EFOR HIGHER AREA MORE HEAT IS AVAILABLE THAN SMALL AREA,SO EVAPORATION BECOMES FASTER.FURTHER EXPLATION IS THAT EVAPORATION IS A SURFACE PHENOMENON.AS HEAT INCREASES THE KINETIC ENERGY OF PARTICLES ALSO INCREASES,SO THE PARTICLES ARE ABLE TO OVERCOME THE FORCE OF ATTRACTION AND GET CONVERTED INTO VAPOUR.WHILE THIS PROCESS IS SLOW WHEN THE SURFACE AREA IS SMALL.
If the fluid is made up of large charged molecules, the molecules will escape at a slower rate because more energy is required to lift their mass and overcome their electromagnetic interactions with each other to allow the molecules to escape. Also, a mixed fluid can evaporate faster or slower depending on how the different molecules interact with each other.
